Copy number loss within chromosome 12 short arm (12p) has gained attention as an adverse cytogenetic marker in multiple myeloma. The prognostic significance and characterisation of the common minimal deleted region remains controversial between various studies with loss of CD27 proposed as the putative critical gene. We aimed to determine the frequency of 12p loss, its correlation with adverse cytogenetic markers further to define and characterise 12p deletions. Our study included a prospective cohort of 574 multiple myeloma patients referred for cytogenetic testing, including interphase fluorescence in situ hybridisation for IGH (14q32.33) translocations and chromosome microarray. Loss of 12p was detected in 54/574 (9.4%) patients and when compared with the non-12p loss group [520/574 (90.6%)], 12p loss patients demonstrated a statistically significant association with specific recurrent cytogenetic markers complex molecular karyotypes (98.1% vs 45.2%), 1p loss (50.0% vs 20.2%), t(4;14) (20.4% vs 7.7%), 8p loss (37.0% vs 15.0%), 13/13q loss (70.4% vs 41.7%), and 17p loss (33.3% vs 6.5%). The size and location of 12p losses were heterogeneous with a common 0.88 Mb minimally deleted region that included ~9 genes from ETV6 to CDKN1B in 52/54 (~96.3%) patients but did not include CD27. Our findings support 12p loss being a secondary chromosome abnormality frequently co-occurring with adverse cytogenetic markers and complex molecular karyotypes indicative of chromosome instability.

Enuresis, defined as intermittent incontinence occurring exclusively during sleep, affects 4-19% of children, but can be effectively treated using education and alarm-bell therapies. However, delays in treatment are likely to impact upon the quality of life of the child, parents and carers. Poor quality and incomplete referrals are thought to be a major driver of inefficiencies. The aim of this study was to explore characteristics of enuresis referrals on the waiting list for a general medicine clinic at a tertiary paediatric hospital.

An audit was conducted to examine all enuresis referrals on the general medicine outpatient clinic waiting list in February 2019 at The Royal Children's Hospital, Melbourne. Enuresis referrals with an organic cause and those for children less than 5 years of age were excluded.

Of the 2613 referrals on the general medicine waiting list, 486 of 2613 (19%) were related to enuresis. The median age of patients on the waiting list was 8 years and 65% (315/486) were male. selleck compound Sufficient detail was provided to determine temporal and disease stratification in 45% (218/486) of referrals; primary versus secondary enuresis, and monosymptomatic versus non-monosymptomatic enuresis. The mean number of days on the waiting list calculated at the time of data extraction (13 February 2019) was 226 (±179) days.

The findings from this study suggest that there are long waiting times for enuresis services and referrals often do not contain complete information.

In response to the increasing burden of cancer in Tanzania, the Ministry of Health, Community Development, Gender, Elderly and Children launched National Cancer Treatment Guidelines (TNCTG) in February 2020. The guidelines aimed to improve and standardize oncology care in the country. At Ocean Road Cancer Institute (ORCI), we developed a theory-informed implementation strategy to promote guideline-concordant care. As part of the situation analysis for implementation strategy development, we conducted focus group discussions to evaluate clinical systems and contextual factors that influence guideline-based practice prior to the launch of the TNCTG.

In June 2019, three focus group discussions were conducted with a total of 21 oncology clinicians at ORCI, stratified by profession. A discussion guide was used to stimulate dialogue about facilitators and barriers to delivery of guideline-concordant care. Discussions were audio recorded, transcribed, translated, and analyzed using thematic framework analysis.

ctors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline-concordant cancer care in Tanzania and comparable settings.

This study provides an assessment of cancer care delivery systems in a low resource setting from the unique perspectives of local multidisciplinary oncology clinicians. Situational analysis of contextual factors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline-concordant cancer care in Tanzania and comparable settings.

Some patients have late recurrence after acutely successful radiofrequency catheter ablation (RFCA) of premature ventricular complexes (PVCs). The aim of this study was to evaluate predictors of long-term success following acutely successful PVC RFCA.

We identified consecutive patients at our institution with frequent PVCs undergoing RFCA and reviewed procedural data and medical records. Acute success was defined as elimination of targeted PVCs for at least 30-min after RFCA. Long-term success was defined as absence of targeted PVCs during all follow-up visits and PVC-burden <5% on follow-up monitoring.

Among 241 patients (mean age 57 ± 15 years, 58% male), 161 (66.8%) had long-term success with median follow-up of 17.7 (IQR, 12.2-29.8) months. Unadjusted predictors of late PVC recurrence were increasing age, diabetes mellitus and alcohol use, while female-sex, shorter ablation-time, right ventricular PVC-origin, single PVC morphology, and earliest bipolar activation ≥24 ms pre-QRS were predictors of long-term success.
